Driving your vehicle
A limited slip differential if equipped, is for
the rear wheel differential only. The fea-
tures of this limited slip differential are
described below;
Just as with conventional differential, the
wheel on one side is allowed to turn at a
different speed from the wheel on the
other side when the vehicle is cornering.
The difference between the limited slip
differential and a conventional differential
is that if the wheel on one side of the
vehicle loses traction, a greater amount
of torque is applied to the rear wheel on
the other side to improve traction.
WARNING
To avoid injury, never run the
engine with one wheel off the
ground,such as when changing a
tire.
WARNING
• Avoid high cornering speed.
• Do not make quick steering wheel
movements,such as sharp lane
changes or fast,sharp turns.
• The risk of rollover is greatly
increased if you lose control of
your vehicle at high speeds.
• In a collision crash, an unbelted
person is significantly more likely
to die compared to a person
wearing a seat belt.
•Loss of control often occurs if
two or more wheels drop off the
roadway and the driver over
steers to re-enter the roadway.
• In the event your vehicle leaves
the roadway, do not steer sharply.
Instead,slow down before pulling
back into the travel lanes.

Power brakes
Your vehicle has power-assisted brakes
that adjust automatically through normal
usage.
In the event that the power-assisted
brakes lose power because of a stalled
engine or some other reason, you can
still stop your vehicle by applying greater
force to the brake pedal than you nor-
mally would. The stopping distance, how-
ever, will be somewhat longer.
When the engine is not running, the
reserve brake power is partially depleted
each time the brake pedal is applied. Do
not pump the brake pedal when the
power assist has been interrupted.
Pump the brake pedal only when neces-
sary to maintain steering control on slip-
pery surfaces.
In the event of brake failure
If service brakes fail to operate while the
vehicle is in motion, you can make an
emergency stop with the parking brake.
The stopping distance, however, will be
much greater than normal.
BRAKE SYSTEM
WARNING -Brakes
• Do not drive with your foot rest-
ing on the brake pedal. This will
create abnormal high brake tem-
peratures, excessive brake lining
and pad wear, and increased
stopping distances.
• When descending a long or steep
hill,shift to a lower gear and
avoid continuous application of
the brakes. Continuous brake
application will cause the brakes
to overheat and could result in a
temporary loss of braking per-
formance.
• Wet brakes may result in the vehi-
cle not slowing down at the usual
rate and pulling to one side when
the brakes are applied. After
going through water, apply the
brakes lightly to regain smooth
braking performance.
WARNING- Parking brake
Operating the parking brake while
the vehicle is moving at normal
speeds can cause a sudden loss of
control of the vehicle. If you must
use the parking brake to stop the
vehicle, use great caution in apply-
ing the brake.

To release the parking brake, pull the
handle up slightly and push the release
button, then lower the handle to the
released position while holding the but-
ton in.Check the brake warning light by turning
the ignition switch ON (do not start the
engine). This light will be illuminated
when the parking brake is applied with
the ignition switch in the START or ON
position.
Before driving, be sure the parking brake
is fully released and the brake warning
light is off.
If the brake warning light remains on
after the parking brake is released, there
may be a malfunction in the brake sys-
tem. Immediate attention is necessary.
If at all possible, cease driving the vehi-
cle immediately. If that is not possible,
use extreme caution while operating the
vehicle and only continue to drive the
vehicle until you can reach a safe loca-
tion or repair shop.
WARNING- Parking brake
• To prevent unintentional move-
ment when stopped, do not use
just the gear shift lever to hold
the vehicle in position. Set the
parking brake AND make sure the
gearshift lever is securely posi-
tioned in 1st (First) gear or R
(Reverse) for manual transmis-
sion equipped vehicles and in P
(Park) for automatic transmission
equipped vehicles.
• Never allow a person who is unfa-
miliar with the vehicle or children
to touch the parking brake. If the
parking brake is released unin-
tentionally,serious injury may
occur.

• Even with the anti-lock brake system,
your vehicle still requires sufficient
stopping distance. Always maintain a
safe distance from the vehicle in front
of you.
• Always slow down when cornering.
The anti-lock brake system cannot pre-
vent accidents resulting from exces-
sive speeds.
• On loose or uneven road surfaces,
operation of the anti-lock brake system
may result in a longer stopping dis-
tance than for vehicles equipped with a
conventional brake system.
✽
NOTICE
When you jump start your vehicle
because of a drained battery, the engine
may not run as smoothly and the ABS
warning light may turn on at the same
time. This happens because of the low
battery voltage. It does not mean your
ABS is malfunctioning.
 Do not pump your brakes!
 Have the battery recharged before
driving the vehicle.
ABS
W-78
CAUTION
• If the ABS warning light is on and
stays on, you may have a problem
with the ABS system. In this case,
however, your regular brakes will
work normally.
• The ABS warning light will stay
on for approximately 3 seconds
after the ignition switch is ON.
During that time, the ABS will go
through self-diagnosis and the
light will go off if everything is
normal. If the light stays on, you
may have a problem with your
ABS system. Contact an author-
ized Kia dealer as soon as possi-
ble.
CAUTION
• When you drive on a road having
poor traction,such as an icy road,
and operate your brakes continu-
ously, the ABS will be active con-
tinuously and the ABS warning
light may illuminate. Pull your car
over to a safe place and stop the
engine.
•Restart the engine. If the ABS
warning light is off, then your
ABS system is normal.
Otherwise, you may have a prob-
lem with the ABS. Contact an
authorized Kia dealer as soon as
possible.

Power steering
Power Steering uses energy from the
engine to assist you in steering the vehi-
cle. If the engine is off or if the power
steering system becomes inoperative,
the vehicle may still be steered, but it will
require increased steering effort.
Should you notice any change in the
effort required to steer during normal
vehicle operation, have the power steer-
ing checked by an Authorized Kia Dealer.
✽
NOTICE
If the power steering drive belt breaks
or if the power steering pump malfunc-
tions, the steering effort will greatly
increase.
✽
NOTICE
If the vehicle is parked for extended
periods outside in cold weather (below -
10°C/14°F), the power steering may
require increased effort when the engine
is first started. This is caused by
increased fluid viscosity due to the cold
weather and does not indicate a mal-
function.
When this happens, increase the engine
RPM by depressing accelerator until the
RPM reaches 1,500 rpm then release or
let the engine idle for two or three min-
utes to warm up the fluid.
STEERING WHEEL
CAUTION
Never hold the steering wheel
against a stop (extreme right or left
turn) for more than 5 seconds with
the engine running. Holding the
steering wheel for more than 5 sec-
onds in either position may cause
damage to the power steering
pump.

The Electronic Stability Control (ESC)
monitors information from various vehicle
sensors and then compares the driver's
commands with the actual behavior of the
vehicle. If an unstable condition occurs - a
sudden evasive movement for example -
ESC intervenes within fractions of a
second via the engine computer and
brake system and attempts to stabilize
the vehicle.
ESC operation
ESC ON condition
• When the ignition is turned
ON, ESC and ESC OFF indi-
cator lights illuminate for
approximately 3 seconds,
then ESC is turned on.
• Press the ESC OFF button
for at least half a second after
turning the ignition ON to turn
ESC off. (ESC OFF indicator
will illuminate). To turn the
ESC on, press the ESC OFF
button (ESC OFF indicator
light will go off).
• When starting the engine,
you may hear a slight ticking
sound. This is the ESC per-
forming an automatic system
self-check and does not indi-
cate a problem.
When operating
When the ESC is in operation,
ESC indicator light blinks.
• When the Electronic Stability
Control is operating properly,
you can feel a slight pulsation
in the vehicle. This is only the
effect of brake control and
indicates nothing unusual.
• When moving out of the mud
or slippery road, pressing the
accelerator pedal may not
cause the engine rpm (revo-
lutions per minute) to
increase.
